I slip a portion of an old t-shirt (portions actually) in between the trim and the body. Working from one end of the trim I carefully pull the trim back just a little. Then I insert another bit-o-shirt just beyond the first clip and apply a little pull. Slowly I work my way down the trim in a 1 - 1,2 - 1,2,3 - 1,2,3,4 fashion.
